Application filed June 17, 1909. Serial No. 562,698.

T 0 all whom itgnay' concern:

- Be it known that I, OLIVER M. Eownnns, a citizen of the United States,residing in the city of Syracuse, county of Onondaga, State of New York,have invented a certain new and useful Improvement in Sash-HoldingDevices, of which the following is a full, clear, and exact.description, reference being had to the drawing accompanying the same.

My invention relates generally to holding or locking devices for windowsand similar structures; and more particularly to that class which isprovided with a shaft. to which the holding or looking dog is secured.()ne object of my invention is to provide a holding or locking device ofthe class mentioned having a shaft which controls the.

looking or holding dog with a support adapted to resist the 'thrustgiven to the dog, as by a falling sash or otherwise.

Another object is to provide such a holding or locking device with acasing, a portion of which projects from the surface on which it ismounted and is adapted to receive the shaft and operating means therefortheprojecting portion of the casing being adapted to form a portion ofthe operating means.

Another object isto provide a holding or locking device having a shaft,one arm of which serves as the holding or looking dog with a casingadapted to be mounted on and project from the-surface of the sashwithout letting the shaft of the holding device for its-whole diameterinto the stile or sash to which the casing is attached,thereby'permitting-of the extension of theshaft and casing to theextreme edge of the sash without unduly weakening the same orinterfering with the stop bead on the frame behind which the holding orlocking-dog is arranged.

Another object is to provide such a hold.-

-ing or locking device with a cewing forming a support for the shaft andthat portion of the dog opposite the end thereof which receives thethrust 1n holding the sash in the open position.

Other objects will appear from the description hereinafter given.

The invention .consists in the combinations herein set forth andparticularly pointed out in theclaims hereunto an exed and which form aportio of thisSpecificatiOn.

F gure 1 shows mfi'ont elevation the corner portion of a window sash andframe to which is attached one embodiment ofJny invention, a portion ofthe guideway opposite the holding or looking dog being broken away forthe better illustration of the parts there shown. Fig. 2 shows invertical section the window frame with the sash and a portion of theholding meansin side elevation as seen on line 2 2 of. Fig. 1. sholvs inhorizontal section that which is seen on line 3-3-of Fig. 1, but withthe guideway complete and the dog in posi- Patented Dec. *7, 1909.

tion for the holding device to hold the sash at that point tightly inthe window frame. Fig. 4 shows in vertical section that which is seen online l l of Fig. 1 when looking from left to right.

Like letters of reference, wherever they I occur, indicate correspondingparts ofthe several figures of the drawing.

In practice it has been found desirable to make window sash, such forinstance as are usually used in passenger cars, withcomparatively thinstiles and when holding or locking-means havin'g a shaft with armsattached thereto for-holding the sash in the desired position areapplied tosuch sashes the shaft portions of such devices have to beeither so placed on the sash that the stop bead against which. the dogof the holding device acts is some distance away from the sash, which isobjectionable, or the shaft portion of the device has to belet into thestile which unduly weakens the sash. It is desirable in this class ofsash holding locking devices having a shaft'which is provided with anarm to serve as a dog or holding part that such w-hi'ch coact with theguideway and form an ornamental trim or finish to such guidewayin whichthe sash moves in opening'and."

A represents the Window the guideway a, in which the sash moves, aportion of which may be removable or notes desired, and B represents thewindow sash to which the dog or holding art and easing are attached, sothat such he ding device is carried bylthe sashand moved correspondinglyas the sash moves. The holding holding device is used in the manner seenin the drawing the fore finger of the hand or locking device C has acasing 0 in which .the shaft D provided with an arm (1 preferably formedintegral therewith, as shown, is mounted, so as to have partial rotationin its bearings formed in the casing. The casing 0 is preferablyprovided with'flanges having laterally extending ears or portions whichpoint in opposite directions, as shown, which are adapted to receivescrews or other fastening devices for securing that portion of thecasing firmly to the sash, the other end of the casing being preferablywithout ears and adapted to receive fastening or other securing means bywhich it may be secured in positionon the sash. These laterallyextending ears are somewhat widely separated from one another and,consequently, that portion of the casing which is most liable todisplacement or damage in use is securely held to the sash. Theformation of the flange portions of the casin as showmpermits of theseholding devices being used on sashes having extremely narrow bottomrails and side stiles as the end of the'casing farthest from the holdingdevice may extend along the bottom rail while the extending ears areattached to the side stile and one ear portion may extend considerablybeyond the point where the bottom rail joins the side stile. The casing0 has the extension 0 which extends, as seen in Figs. 1 and 2, to theedge of the sash B which is in the guideway a of the window frame. Theextension 0 with the inwardly projecting portion of the casing is preferably arranged relatively to the shaft 1) as shown, so that no portion ofsuch extension extends beyond the outer line of such shaft and there isa greater thickness of material adjacent to nearly opposite portions ofthe shaft than there is between such portions, is more particularly seenin Figs. 3 and 4c of the drawings, that is, ,there is a less thicknessof material in the casing and extension at the bottom of the depressionthan there is near the outer edges thereof. This permits of the sashbeing cut to a less depth than would be the case if the semicircularportion of the extension and easing, which is'to be received in thedepression in the sash, were concentric with the axis of the shaft. Thisarrangementof the extension e and casing affords the same support to theshaft 4 and holding dog that would be afforded if such portions wereconcentric with such axis. The outwardly circular projecting portion ofthe casing c is preferably arranged substantiallyconcentric with theaxis of the shaft D and it is preferably provided with a still furtherprojecting portion which, with the circular portion, forms a portion ofthe operating means 0 by which the sash is opened and closed and theshaft D moved sufficiently to release the sash and permit it 54 0 movefreely-in the guideway. lVhen the of the operator engages with the underside of the projecting portions of the casing and such portions form alift by which the sash can be lifted in opening the same. Such portionsalso form a support for the hand of the operator when he grasps orpresses down upon the movable part of the operating means with his thumbin controlling the holding dog and the movements of the sash. As shownthe movable portion '0' of the operating means is the upper one of thetwo seen in Figs. 1, 2 and 4 of the drawings and tomove the dog out ofholding position such upper portion is moved toward the fixed orstationary lower 'portion 0 which forms the lift for the sash; It willbe observed that theprojecting portions of the casing do not interferewith the use of the device as the operating means are actuated preciselythe same and occupy no more space than they would occupy if there wereno projecting circular portions of the casing.

The shaft D has mounted thereon a spring S, the tension of which tendsto move the holding or locking dog into holding or looking position. Theshaft D is also provided with operating means 0 consisting, as shown, ofa stationary lift or finger piece 0 prefcrably'formed integral with thecars ing 0 and a thumb or movable finger piece 0 preferably secured tothe shaft 1), the parts 0 and 0 being so related to one another thatwhen the movable fingeror thumb piece 0' is moved toward the stationaryportion 0, the free end of the holding dog will be moved toward the'sashB and thereby be moved out of holding position, releasing the sash so asto permit it to move freely in the guideway.

It will be observed that the spring S and the parts 0 and 0 formoperating means by which the holding or locking dog is moved in onedirection by the tension of the spring and such dog is moved in theopposite direction by the movable thumb or finger piece 0 being movedagainst the tension of such spring. It will also be observed that thefree end of the part 0 will move in a circle concentric with the axis ofthe shaft D and consequently the circular portion of the casingavill notinterfere with the use of the operating means.

The form of holding or locking means herein shown may be used inconnection with a sash and frame such as are herein set forth havingsurfaces for the holding or looking dog to coact with of the form shownin Figs. 1 and 2. or with sashes and frameshaving bthcr specific formsof coacting surfaces ibr the holding or locking dog and other surfacesfor such'dog to coact with, as desired. These coacting surfaces may beformed on a strip, as I, or they may be other- .lll)

wise formed as desired. When used as herein shown the surface e on dog(Z engages wlth the surface 2' on the strip I attached to the frame ofthe window in the guideway to guideway by the tension of the spring Sacting on the dog d through the shaft D.

Also the surface e of the dog d engages with the surfaces 2' on thestrip I secured to the frame in the guideway, and pressure' 'appliedtosuch surface e tends to move the opposite portion of the dog (Z intoclose contact with the support formed on the extension 0 of the casing.The surfaces and the dog as (Z may be formed as herein shown or in anyother desired manner adapted to do the work of holding the sash in theguideway, as the specific form ofsurfaees for the dog, as d, and thesurfaces with whichthe dog coacts do not form aness ential part of thepresent invention.

\Vhat I have herein shown and described will naturally suggest to thoseskilled in this art somewhat different embodiments of this inventionthan the specific one herein illus trated, therefore, I do not wishtolimit myself to the one herein set forth, but wish to include allembodiments which contain the spirit of this invention as particularly Ypointed out in the claims hereunto annexed forming a portion of thisspecification.
